Rolling luggage system

ABSTRACT

A luggage system is shown and described. The system comprises a first piece of rolling luggage having a first laterally extendable handle assembly; a second piece of rolling luggage having a second laterally extendable handle assembly; and a connection device. The connection device comprises a first-interface mated with the first handle assembly; a second-interface releasably mated with the second handle assembly; and a connector connecting the first-interface to the second-interface.

BACKGROUND

(1) Field

The present disclosure relates generally to rolling luggage and more particularly to pieces of operably connected luggage, and even more particularly, to a device for operably connecting pieces of rolling luggage.

(2) Description of Related Art

Rolling luggage is known in the art. FIG. 1 shows one example of rolling luggage 2. Luggage 2 includes a luggage compartment 4 to which wheels 6 are operably attached. An extendable handle 10 extends laterally from compartment 4. Handle 10 retracts and can be stored within compartment 4 when desired.

When traveling with one piece of rolling luggage, a traveler holds handle 10 of the luggage in one hand and pulls the luggage substantially directly behind him as he walks, applying force in the direction of arrow 8. To ensure that the luggage rolls properly, the traveler usually must turn their shoulder slightly rearwardly in the direction of the hand holding handle 10 to ensure a substantially linear arrangement of force 8, handle 10, and wheels 6.

When traveling with two pieces of rolling luggage, a traveler will hold the handle of one piece of luggage in one hand and hold the handle of the other piece of luggage in the other hand. FIG. 2 a, for example, shows a traveler 1 rolling luggage 2 a and 2 b. Traveler 1 is moving and applying force in the direction of arrow 8. In such situations, traveler 1 cannot turn both shoulders rearwardly, and as a result is typically required to hold both arms slightly out to the side to ensure proper alignment of force 8 and handle 10 to move the luggage in the desired direction, e.g., the direction 8 a and 8 b. The slight elevation of the arms, in combination with the continuous adjustment of handle 10 to ensure proper direction, can become tiring to a traveler, particularly, if the traveler is required to cover large distances, e.g., from terminal to terminal in an airport. Alternatively, as shown in FIG. 2 b, traveler 1 may attempt to position both luggage 2 a and 2 b rearwardly or behind the traveler's back as the traveler moves forward. This type of positioning may result in luggage collision, which may send luggage in undesirable directions, e.g., 8 c or 8 d. Both of the above strategies have additional shortcomings, because by occupying both of the traveler's hands, they make it very difficult for the traveler to perform other tasks, e.g., talking on the phone or reading airplane ticket information. Furthermore, both current strategies make it difficult for the traveler to navigate crowded areas.

It is to these, and additional problems, that the present invention is directed.

FIG. 10 also shows interface 230 mated to support rod 232. In this embodiment, interface 230 includes pin 234 positioned within aperture 232 a defined by rod 232. Pin 234 is secured by attaching member 236 to the terminal end 234 a of pin 234, thereby preventing pin 234 from traveling back through aperture 232 a.

As will be appreciated from the above description and attached figures, systems of the present invention enable travelers to transport at least two pieces of luggage using only a single hand. In most embodiments, travelers will simply extend handle assemblies, align the rolling luggage, and connect the first- and second-interfaces to the handle assemblies. The traveler may then grasp the first piece of luggage and proceed on their way, at which time, the second piece of luggage will follow safely and securely behind. The system may also be quickly disassembled as desired, for example, to board a plane or store the pieces of luggage. While in most embodiments, both the first- and second-interfaces will be releasably attachable to both the first and second handle assembly, in certain embodiments of the system, one of the interfaces of the connection device may be fixed to the handle assembly, e.g., as ring positioned around a handle or support rod. In these embodiments, the connection device would remain attached to the first piece of luggage, and may be stored, for example, in a pocket on the luggage when not in use. It may also be desirable to incorporate additional pieces of luggage and additional connection devices, for example, for a baggage handler or bell hop who may be required to regularly move numerous pieces of luggage. All such embodiments are considered to be within the scope of the present invention. Further, those of ordinary skill will recognize that any combination of the above disclosed embodiments are inclusive of the present invention.
